Bridge floor connecting structure based on separation design, simply supported girder bridge and construction method
The invention relates to the technical field of bridge deck continuous simply supported girder bridge design and construction, in particular to a bridge deck connecting structure based on separation design, a simply supported girder bridge and a construction method. On the basis of the thought that quick-wear parts avoid a driving surface, bridge deck connecting structures of the simply supported beams are separately designed, bridge deck rigid connection structures are designed to serve as horizontal force transmission components of the simply supported beams, bridge deck simply supported arch structures are designed to serve as structural joint transition components of the simply supported beams, and therefore all kinds of stress between the simply supported beams are treated separately. A bridge deck rigid connection structure is in rigid connection with bridge decks of main beams on the two sides, a bridge deck simply-supported arch structure is connected with the main beams on the two sides and a cast-in-place leveling layer without any steel bars, and a vertical pull rod with pretension is further arranged between the bridge deck simply-supported arch structure and the bridge deck rigid connection structure. Compared with the prior art, the novel bridge floor connecting structure, the simply supported girder bridge and the construction method are safer, more economical, more practical, more durable and more reliable, and can be widely applied to various roads and municipal bridges.
本发明涉及桥面连续简支梁桥设计和施工技术领域，特别涉及一种基于分离设计的桥面连接结构、简支梁桥及建造方法。本发明基于易损件避开行车面的思路，将简支梁的桥面连接结构分离设计，分别设计了桥面板刚接结构作为简支梁的水平传力构件、桥面简支拱形结构作为简支梁的结构缝过渡构件，从而将简支梁间的各项受力分而治之。其桥面板刚接结构与两侧主梁的桥面板刚接，桥面简支拱形结构与两侧主梁及现浇调平层之间均无任何钢筋连接，在桥面简支拱形结构与桥面板刚接结构之间还设有带预张力的竖向拉杆。本发明是相比现有技术更为安全、经济、实用、耐久、可靠的新型桥面连接结构、简支梁桥及建造方法，在各类公路和市政桥梁中均可广泛应用。
